I'm trying to update Zen11SP1 to SP2 on SLES 10SP4 using the ISO downloaded from Novell. The install stops at the initial "License Agreement" screen, never displaying the "Next" button and not displaying any license agreement. The only button that works is the "Help" button. All other buttons or options are grey. I've already downloaded another copy of the ISO. The server is a VM running on VMWare ESX 4.0. Any ideas?
